i think 92 was the last you could de cat. i did a 90 gsi 3000 24v and a 92 gsi 3000 24v and a 92 senny 12v, when done with a nice free flowing exhaust system, they needed to be chipped to fuel properly at wide open throttle, as lambdas werent used at wide open and they fell back to preset maps( which caused them to run slightly weaker) if i remember rightly. if the mig fails, ill cut the pipes weld on flanges bolt em in and give the four, i still have from two them cars another outing! with the option, then of decat between mots...niccce, should give a good bit of time to learn how to fool the computer, im thinking it may be possible to use resistors in conjunction with the sensors either in series or parralell depending on which way voltage needs moving. to modify the sensor voltage returns, so the computer can still use the sensors to make adjustments but thinks all is good, what do you reckon kev? may also be possible to cure 420, 430 like this without moving anything, by moving sensor returns back into spec?
